This paper discusses an efficient approach to design and implement a highly
available peer- to-peer system irrespective of peer timing and churn. Although
peers in P2P system join or leave at whim, it has been found that most of the
peers follow diurnal pattern of availability governed by the time of day
effect. When considering a global P2P system, the cyclic behavior of peers
situated on diff?erent time zones can be found complementary of one another.
Our approach utilizes the diurnal pattern of globally dispersed peers to
develop a grouping strategy.
